Being a millionaire gives you more power to take risks. With that amount of money, you also get more influence and resources to experiment on personal projects. You could create a charity for a disease that doesn't get much attention in the mainstream media. So, to answer your burning question, how can I become a millionaire? , you need to develop a million-dollar mentality.
Don't worry, I won't tell you to make a vision board (unless you want to). Investing your money is the way to become a millionaire fast. The two most common types of retirement accounts are IRAs, which are personal accounts, and 401 (k), which are generally offered through work. You can have both types and both allow you to invest in the stock market while saving money on taxes. If you contribute as much as you can to these accounts, it's like the fast track to becoming a millionaire.
Today, there is an all-time high for both 401 (k) millionaires and IRA millionaires, which means that people become millionaires just by investing in these accounts.
